Document.forms

The forms read-only property of the Document interface returns an HTMLCollection listing all the <form> elements contained in the document.

Note: Similarly, you can access a list of a form's component user input elements using the HTMLFormElement.elements property.

Syntax

collection = document.forms;

Value

An HTMLCollection object listing all of the document's forms. Each item in the collection is a HTMLFormElement representing a single <form> element.

If the document has no forms, the returned collection is empty, with a length of zero.
